The Official Languages Act allows the government to adopt regulations to guide the federal administration in the application or implementation of various provisions of the act, or to make them more specific. Until now, after 35 years of official bilingualism, the government has only adopted one single regulation which concerns one aspect of the act alone, namely the part which deals with services to the public.
I mainly made my recommendation to modernize the existing regulations, which are really outdated, all the more so because in the last 10 to 15 years, we have noticed that the quality of services has stagnated. Further, the government has changed the way it serves its citizens. Just think of Government-on-line.
Your question was about the language of work or Part VII. Again, under the act, federal institutions must respect the right of employees to work in the language of their choice. Consequently, in Quebec, anglophones have the right to work in their language in federal institutions, and francophones can do the same too, of course.
I expect there will be regulations on the language of work, because I think that the right of employees to work in the language of their choice is not really being recognized. French is still generally underrepresented within the federal government. In Quebec, the right of anglophone employees to work in their language is not respected either within federal institutions, and the same goes for Quebec francophone employees, more specifically when they communicate with Ottawa or with the headquarters of a federal organization.
